That's my point, and I said this in the last post. A larger frontal diameter bullet going through the animal transferring more disruption to the CNS vs a smaller diameter bullet of similar construction, would allow said larger diameter bullet to have an effect to some degree not unlike a smaller diameter bullet that fragments and disrupts CNS. My experience with mono (controlled expansion) bullets of a larger diameter over many years and animals is a-typical to what a number of others, your experience included, have shared with mono bullets or controlled expansion bullets of smaller diameter vs the same diameter fragmenting bullets.
Just thinking out loud. It's established fragmenting bullets do a fantastic job. Most comparisons based on experience of the hunter is of controlled expansion bullets of the same initial diameter as the fragmenting bullets, like in your very good example.
